[McIDAS #CNE-889859]: Setting up ADDE server

Hi Mike,

Thanks for giving me a login to both wxsession and wxsat.  This allowed me to
figure out what why a McIDAS DSINFO query as user 'unisup' would not show
information for the ER dataset hosted on wxsat.

The problem is in how the MCCOMPRESS environment variable is being set for
your user(s).  Upon login to wxsession, 'echo $MCCOMPRESS' showed:

[unisup@wxsession ~]$ echo $MCCOMPRESS
TRUE

The McIDAS-X v2006 installation on the remote ADDE server machine has moved
away from use of ports 500/503 (for uncompressed and 'compress' compressed
transfers, respectively) to exclusive use of port 112 for uncompressed and
gzip-compressed transfers.  This necessitates switching the definition of
MCCOMPRESS in user sessions to either GZIP for gzip-compressed or NONE
for no compression; I recommend using GZIP.  MCCOMPRESS defined to be TRUE asks
for 'compress' compressed transfers, and neither of your machines has 
compress/uncompress
installed (or, if it is, it is not in the PATH being used by users).

I looked for a .cshrc file for the user 'unisup' on wxsession and did not
find one even though the SHELL for 'unisup' is Tcsh.  This implies that
you are using a different method to define needed environment variables
for McIDAS users.  You should review what you are doing and update it to
at least specify MCCOMPRESS as GZIP.

After setting MCCOMPRESS=GZIP as 'unisup' on wxsession, the remote access
to wxsat works fine:

<logged in as 'unisup' on wxsession>
setenv MCCOMPRESS GZIP
dataloc.k ADD ER wxsat.db.erau.edu

By the way, while I was investigating things on wxsat, I noticed that the
user 'mcadde' had /bin/bash set as its default shell.  My recommendation
is to set the 'mcadde' account to have no login, so I changed its default
shell to be /sbin/nologin and set it to have no password (both actions done
using 'vipw' as 'root').

Cheers,

Tom
